Pipe lifting assembly
Abstract
A pipe lifting assembly includes an eyebolt that is insertable into a pipe. A pair of spreaders is provided and each of the spreaders is slidably positioned around the eyebolt. Each of the spreaders is positionable at a selected point along the eyebolt, and the pair of spreaders includes an upper spreader and a lower spreader. A plurality of grips is each pivotally coupled between each of the spreader. Each of the grips is spaceable a selected distance from the eyebolt when the upper spreader is moved upwardly or downwardly along the eyebolt. Additionally, each of the grips frictionally engages an interior surface of the pipe when the eyebolt is positioned in the pipe and the upper spreader is moved downwardly along the eyebolt. In this way each of the grips facilitate the pipe to be lifted when the eyebolt is lifted.
Claims
exact text as granted — not AI-modifiedI claim:
1. A pipe lifting assembly being configured to frictionally engage an interior surface of a pipe thereby facilitating the pipe to be lifted, said assembly comprising:
an eyebolt being insertable into a pipe, said eyebolt having a first end, a second end and an outer surface extending therebetween, said outer surface being threaded, said eyebolt having a length of at least 11.0 inches, an eye of said eyebolt being positioned on said second end;
a cap being coupled to said first end of said eyebolt, said cap having an outside diameter being greater than an outside diameter of said eyebolt;
a pair of spreaders, each of said spreaders being slidably positioned around said eyebolt, each of said spreaders being positionable at a selected point along said eyebolt, said pair of spreaders including an upper spreader and a lower spreader, said lower spreader resting on said cap such that said lower spreader is inhibited from passing downwardly beyond said cap, said upper spreader being positioned between said lower spreader and said eye on said eyebolt, each of said spreaders comprising a block having a top end, a bottom end and an outer surface extending therebetween, said block having an aperture extending through said top and bottom ends, said eyebolt extending through said aperture such that said block is slidable on said eyebolt, said outer surface having a plurality of intersecting sides, each of said intersecting sides having a coupling being attached thereto, said bottom end of said block of said lower spreader abutting said cap;
a plurality of grips, each of said grips being pivotally coupled between each of said spreaders, each of said grips being oriented collinear with said eyebolt, each of said grips being spaceable a selected distance from said eyebolt when said upper spreader is moved upwardly or downwardly along said eyebolt, each of said grips frictionally engaging an interior surface of the pipe when said eyebolt is positioned in the pipe and said upper spreader is moved downwardly along said eyebolt wherein said grips are configured to facilitate the pipe to be lifted when said eyebolt is lifted, each of said grips disengaging the interior surface of the pipe when said upper spreader is moved upwardly along said eyebolt; and
a nut threadably engaging said eyebolt such that said nut can rotatably travel upwardly and downwardly along said eyebolt, said nut being positioned between said upper spreader and said eye of said eyebolt, said nut urging said upper spreader toward said lower spreader when said nut is tightened on said eyebolt, said nut engaging said top end of said block of said upper spreader when said nut is tightened.
2. The assembly according to claim 1 , wherein
each of said spreaders includes a plurality of arms, each of said arms having a primary end and a secondary end, said primary end of each of said arms being pivotally coupled to a respective one of said couplings such that each of said arms is positionable at an upward or downward angle on said block.
3. The assembly according to claim 2 , wherein each of said grips has a first surface and a second surface, said secondary end of each of said arms being pivotally coupled to said second surface of a respective one of said grips, said first surface of each of said grips comprising an abrasive material thereby enhancing said first surface of each of said grips to frictionally engage the interior surface of the pipe.
4. The assembly according to claim 1 , further comprising a spring being positioned around said eyebolt, said spring being positioned between said upper spreader and said lower spreader, said spring biasing said upper spreader to travel away from said lower spreader when said nut is loosened on said eyebolt, said spring being positioned between said top end of said block of said lower spreader and said bottom end of said block of said upper spreader.
5. A pipe lifting assembly being configured to frictionally engage an interior surface of a pipe thereby facilitating the pipe to be lifted, said assembly comprising:
an eyebolt being insertable into a pipe, said eyebolt having a first end, a second end and an outer surface extending therebetween, said outer surface being threaded, said eyebolt having a length of at least 11.0 inches, an eye of said eyebolt being positioned on said second end;
a cap being coupled to said first end of said eyebolt, said cap having an outside diameter being greater than an outside diameter of said eyebolt;
a pair of spreaders, each of said spreaders being slidably positioned around said eyebolt, each of said spreaders being positionable at a selected point along said eyebolt, said pair of spreaders including an upper spreader and a lower spreader, said lower spreader resting on said cap such that said lower spreader is inhibited from passing downwardly beyond said cap, said upper spreader being positioned between said lower spreader and said eye on said eyebolt, each of said spreaders comprising:
a block having a top end, a bottom end and an outer surface extending therebetween, said block having an aperture extending through said top and bottom ends, said eyebolt extending through said aperture such that said block is slidable on said eyebolt, said outer surface having a plurality of intersecting sides, each of said intersecting sides having a coupling being attached thereto, said bottom end of said block of said lower spreader abutting said cap; and
a plurality of arms, each of said arms having a primary end and a secondary end, said primary end of each of said arms being pivotally coupled to a respective one of said couplings such that each of said arms is positionable at an upward or downward angle on said block;
a plurality of grips, each of said grips being pivotally coupled between each of said spreaders, each of said grips being oriented collinear with said eyebolt, each of said grips being spaceable a selected distance from said eyebolt when said upper spreader is moved upwardly or downwardly along said eyebolt, each of said grips frictionally engaging an interior surface of the pipe when said eyebolt is positioned in the pipe and said upper spreader is moved downwardly along said eyebolt wherein said grips are configured to facilitate the pipe to be lifted when said eyebolt is lifted, each of said grips disengaging the interior surface of the pipe when said upper spreader is moved upwardly along said eyebolt, each of said grips having a first surface and a second surface, said secondary end of each of said arms being pivotally coupled to said second surface of a respective one of said grips, said first surface of each of said grips comprising an abrasive material thereby enhancing said first surface of each of said grips to frictionally engage the interior surface of the pipe;
a nut threadably engaging said eyebolt such that said nut can rotatably travel upwardly and downwardly along said eyebolt, said nut being positioned between said upper spreader and said eye of said eyebolt, said nut urging said upper spreader toward said lower spreader when said nut is tightened on said eyebolt, said nut engaging said top end of said block of said upper spreader when said nut is tightened; and
a spring being positioned around said eyebolt, said spring being positioned between said upper spreader and said lower spreader, said spring biasing said upper spreader to travel away from said lower spreader when said nut is loosened on said eyebolt, said spring being positioned between said top end of said block of said lower spreader and said bottom end of said block of said upper spreader.Join the waitlist — get patent alerts
